CALENDAR.

SPECIFICATION forming part of Letters Patent No. 648,835, dated May 1,1905. Application met Lemmy 22,1900. semi 10.2.329. fNc man.;

To @ZZ 107mm z't may concern:

Be it known that I, J OHX M. Brees, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and usefulImprovement in Calendars, of which the following is a specification.

)ly invention is an improvement in perpet ual-date calendars, and hasfor its object a calendar of this class which will embody specieimprovements in the man ner of constructin g and assembling the parts,whereby the calendars may be ver'y cheaply made and will be securelyheld together.

The invention consists in certain details of construction andarrangement of the parts, which will be hereinafter specificallydescribed and claimed. q,

Reference is to be had to the accompanying drawings, forming part of thespecification, in which like characters of reference indicatecorresponding parts in ally the Views.

Figure l is a face view of my improved calendar. Fig. 2 is a similardetail of the ring designating the months. Y Fig. 3 is an enlargedtransverse section of the calendar, and Fig. 4 is a. rear perspective ofthe upper disk.

As shown in the accompanying drawings, my improved calendar comprisessuperposed concentric rings and disks mounted to turn relatively to eachother, and the main feature of myinvention resides in the detailconstruction oi' these rings and disks, whereby they may easily beconnected, as stated above. To this end I provide the ring A, which isdivided, as shown, into twelve radial parts A', each indicating a monthand the number of days in the month, and on said ring A is placed a ringB, of exactly the same inner and outer diameters as the ring A, andwhich is divided into thirty-five equal radial part-s B', thirty-one ofwhich indicate the, days of a month, while an opening B2 is cut in thering B, including the remaining parts, the said opening beingapproximately equal to and adapted to disclose any one of the`monthcompartments A. On the inside of the radial parts B' of the ring Bsaid ring is formed with an annular recess B3, in which is fitted theupper disk O, containing a suitable central advertisement or design anddivided into thirty-live radial parts C', designating thc days of theWeek, as shown. The disk C is further provided with a boss C2, which isjust large enough to fitwithin and extend through the rings B and A, asshown particularly iu Fig. 3, and the ring A is formed on its rear facewith an annular recess A2, in which accurately fits the retainingdisk D,Which is attached to the boss C2, and thereby holds all A the partstogether and enables. them to turn relatively to each other.

I preferablyv make the parts of my improved calendar by cutting them outof sheet metal and stamping them into the proper shape, with the lettersand dates embossed or printed on them; but I may make the parts ofsuiiiciently-light stiff paper or cardboard,in which case thepapcr-retai ning disk Dis pasted to the boss C2, and the disk C, aswellas the annularly-recessed rings A and B, may be conveniently and cheaplymade by pasting together pieces of `stiff paper or cardboard of requiredsize.

It will be noted that my improved calendar canibe Very cheaply andeasily made and very easily assembled, there being no pivot-pins, butthe parts accurately fitting each other and held to turn relatively toeach other in a very simple manner.

I wish it understood that instead of the design shown in theaccompanying drawings both faces of the calendar may be used forpictures, indexes, or advertisements.

Having thus described my invention, what I claim as new, anddesire tosecure by Letters Patent, is Y 1'. A perpetual-date calendar, comprisingsuperposed rings of equal inner and outer diameters adapted tocontaincharacters designating the months and days of a month respectively, saidrings being formed with anf nular recesses on their outer faces, a diskiitting in the recess of the upper ring, said disk being adapted tocontain characters designating the Week and being formed with a bossfitting Within and extending through the superposed rings to and iiushwith the recessed face ofthe lower ring, and a retaining-plate ttedWithin the recess in the lower ring and secured to said boss, as setforth.
